Résumé

Abstract Objective The optimal induction therapy for severe glomerulonephritis of ANCA-associated vasculitis (AAV) is debated. We compared the efficacy of glucocorticoid and rituximab (RTX) or CYC induction therapy for severe AAV-related glomerulonephritis and evaluated the potential benefit of plasma exchange (PE) as adjunct therapy to CYC. Methods This retrospective, multicentre study included AAV patients with severe renal active disease (serum creatinine level ≥350 µmol/l and/or estimated glomerular filtration ratio ≤15 ml/min/1.73 m2). Propensity-score analysis was used to adjust for potential confounders. Results Between 2005 and 2017, 153 patients with AAV-related glomerulonephritis were studied (96 [60%] men; mean [s.d.] age 63 [13.1] years): 19 (12%) were treated with RTX and 134 (88%) with CYC. Remission rates did not differ between RTX- and CYC-treated groups. Although more patients with RTX than CYC were dialysis-free at month (M) 12 (79% vs 68%), the difference was not significant after adjustment. Among 134 patients with CYC-treated glomerulonephritis, 76 (57%) also had PE. M3 and M6 remission rates were comparable for weighted CYC groups with or without PE. For weighted groups, the dialysis-free survival rate with CYC was higher with than without PE at M6 (72% vs 64%; odds ratio 2.58) and M12 (74% vs 60%; odds ratio 2.78) reaching statistical significance at M12. Conclusion We could not find any difference between RTX and CYC as induction therapy for patients with severe AAV-related glomerulonephritis. In patients receiving CYC induction regimen, the addition of PE conferred short-term benefits with higher dialysis-free rate at M12.
